Traditional remedial techniques, such as pump and treat, are often costly and inefficient in recovering free product. Based on extensive experience addressing petroleum and chemical spills, we have deployed the FabEx system on many sites over the past 10 years to recover both light and dense non aqueous phase contaminants (LNAPL and DNAPL), also known as free-phase product. The FabEx system eliminates the need to extract/ treat/ process large volumes of groundwater, minimises or eliminates disposal costs, and reduces O&M costs by 70%.

The simple but highly effective NAPL Fabric Extraction Technique - FabEx - utilises an oleophilic/ hydrophobic fabric capable of adsorbing the product with a 99% recovery efficiency. The fabric is conveyed in a continuous loop into an abstraction well to intercept the oil-water interface. As the fabric travels through the interface, product adheres to the fabric. The adsorbed product is then removed in a specially designed desorption unit and the recovered oil is collected in a storage drum or tank for disposal or recycling.
